Overview

An item reason defines a reason for an item to be in any state and grade. Item reason groups are used to organize similar reasons. An item reason is selected when production or consumption of an item is reported and then this reason determines the state and grade of the lot of an item. A reason can be selected by PLC, I/O, or an operator.

Use the Item Reasons module by selecting the Item Reasons module in the Product Definition group of the Wonderware MES Client to create and maintain item reason groups and reasons. The item reason group and the reasons associated to that reason group are assigned to item classes and entities to specify which reasons are applicable to different item classes or entities.

When you open the Item Reasons module, a list of all the existing item reason groups is shown in the tabbed workspace. You cannot define a reason for an item before defining possible resultant states and grades for that item.

Rejected Production

Rejected production refers to items produced that must be withheld from normal production, often because the product does not meet quality standards. You can track rejected production by using attributes in the Operations Capability Object. This is done by creating a production counter for the rejected production in the Production Counter tab, associated with a Bad Production Item Reason. Use the counter created to track your rejected production.
